Multispectral refers to the use of multiple wavelengths of light to capture information about an object or area. This technique is commonly used in fields like remote sensing, agriculture, and environmental monitoring. By analyzing different wavelengths, scientists can gather data on various features, such as vegetation health or water quality. In multispectral imaging, sensors detect light in specific bands, often including visible light and infrared. This allows for the identification of materials and conditions that may not be visible to the naked eye. Technologies like satellites and drones often employ multispectral sensors to collect valuable data for research and decision-making.
